The' present invention relates,va s indicated, to a stampedratchet die stock, andthe primary Vobjeotfof the invention is'to provide a ratchet diestock made up, to a large extent "5 of stampedparts. Further objects of the invention' will appear' as, the description pro* ceeds. To the accomplishment'of the foregoing 'and related ends, said invention, then, consists of the means hereinafterfully dc- Y scribedand particularly pointed outin the claims.

y The vannexed drawings andthe following descriptionset forth in' detail'certain mecha nism embodying the invention, such disclosed `v1i means constituting, however,lbut one of various mechanical forms infwh'ich theY principle of the invention may be used. VIn said annexedl drawings:v Fig. lis an elevation of a stockconstructed in' accordance with the present invention;

Fig. 2 is a longitudinal section thereof taken substantially on the line 2 2 ofrlig.v 1; Fig. 3 is a side elevation of the handle inember; Fig. 4' is a section' taken substantially 'on the linejlle ofy Fig. 2, andjlooking in the rdirectionof the arrows; and Fig. is a broken frontelevation of the h'andle me1nber. `f Referring vmorel'particularlyto the draw- -so ings,'it will be seen that th'e-'refe'rencenumeral 10 indicates a substantially cylindrical member formed of stamped "sheetinietal, said member being hollow, and Open at 'itfsfoppfo- V,site ends.' At its oneend,saidmember 10' is 35 formed with 'an outwardly projecting annular 'flange 11. A' A diehead-l 12 provided with slots 13 forvreceiving'chasers orcutters' 14 is secured to said llangebyfnieanso'f screws 15', or equivalentfs'ecuringmeans, f l

Said 4,memberl 1'0 "is" formed, vadjacenty its end opposite the flange', 11, with 'a plurality ofv longitudinally extending, V'eq'puidistantly spaced depressions v16, said series completely circumscribingsai'd member 10;v `As will be Vl5 obvious, the depressions 16 define between them, aseries of equidilst'antly spaced teeth 17 '(seeFigly l "i Alhandle member (18 is formed "in its one end with a socket 19 vscrew threadednas rat20 l550 for the recept-ionof an operating bar. The

Vsions 1G andthe teeth 17;

opposite end nof said member. is cylindrical in form as indicated at 21, and is formed with a bore'22 adapted to receive the grooved end of the member 10; When thehandlelS is 1n place on'the member 10,' the bore thereof completely encloses the grooves or depreslVithin an open portion 23, which may be considered a portion of the bore 22, there is mounted a pivot pin 24,y thepin being posiy tioned in paraxial relation to said member 10. A prawl 25 is mounted'on said pin, and said pawl is formed4 with substantially identical opposite ends 2G and 27. Substantially 1nid way between its ends, said pawl is formed with af'cam'28 having a notch 29 in its topmost surfaceL spring leaf is mounted Within said open lportion 23 and has a nose 31. y As will be obvious, the pawl 25'1nay be set in `the position'illustrated, in which position'the nose 31 of the spring leaf 30 bears against the face 32 of the cam 28 to hold the end 27 of said cam resiliently in engage-V ment'with the teethg17 of the member 10. Correspondingly, the pawl may be `set in such a position that the nosef31-of the spring leaf-30 will hold the end 26'of said pawl resiliently'in" operative relation with 'the yte`ethfl17 ofthe member 10.` On theother `hand,*the pawl25 may be set in suchfa posi- -tion that the nose'31 of theleaf 3() willenter thenotch 29 in the cam 2S to hold boththe pawll ends outlof cooperative' relation with the teeth17. y i* In order fto retain vthe handle 18 on the cylindrical member 10, I' provide said cylindrical memberwi'th apunched up lug 33 whichy is adapted to be received 'in an annular groove 34 formed in the portion 21 of fthat, when the lug 33 is inregistrywithv said rslotan end`2G or 27 of the pawl25 will be in registryy with one of the grooves 16; 'This arrangement insures against accidental removal of the handle member 18 from the cylindrical member 10 at all times, since, when the lug 33 is in registry with the slot 35, the pawl 25 will normally be engaged in one of the slots 16, thus preventing material axial movement of the handle member 18 with respect to the member 10, and when the end of said pawl is in registry with one of the teeth 17, the handlemember is held against axial movement by the engagement of the lug 33 in the slot 34. Thus, in order to remove the handle from the cylindrical member 10, it is necessary to bring the lug 33 into registry with the slot 35, and to move the pawl 25 into such a position that neither one of its ends 26 or 27 will engage with the cylindrical member 10.

Other modes of applying the principle of my invention may be employed instead of the one explained, change being made as regards the invention herein disclosed, provided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim as my invention:
